Here's the dash, sanded, cleaned and ready for primer sealer and satin black paint. 10 Lbs whole as it sits now.
I have in the tanks now the interior metal window trim pieces that IIRC weigh all together 6 lbs. They should be half that or less when out of the drink and dry.
The two vertical B-pillar interior trim pieces were relatively flat, so I was able to fabricated them out of aluminum. That in itself saved 2-1/2 Lbs. from 3Lbs.
Fellas, don't forget the lower fender flat stock shims for alignment. A pack of five or so depending on how many it takes to bring the fender out to line can weigh close to a 3/4 Lb. on each side. Aluminum cuts the fat off by half.
